To all whom z't'mag/ concern:-

Be it knownthat I, JOHN J'. citizen of the United :.States, f' residing'v 'at Brooklyn, VKings County,

useful Improve' ments in AXle-Bearing-Repairing Tools, of which the following isa speciicationf I f My invention relates to a'tool `which-is.y designed particularly for `repairing ythe bearf' ings on the'ends of the front `axles ofi/fautomobiles ofwhat maybe calledtheFord type.

Such axles areprovidedat eachl end with a pair of arms or lugs, between which. is se cured the-.arm carrying the-front wheel, 'a

bolt being passed down through the axlellugs and through cooperatinglugsfon the wheel arm, so that the latter is pivotedtothe axle and may be swungpback and forth by meansk of steering mech-anisnnsoasvtogivethe lde-;

sired direction'to the front wheel.

The bolt, which acts as a pivot in connecte; ing the wheel arm and the axle, is customarily threaded through the lower y'azile lug and ,then locked in place by v'a locknut," and z a cotter pin ispassed through'the bolt-. ,y It isfound, inpractice, that this bolt, in

time, becomes/loose in itsy bearings, the

. thread. in the lug becomes wornor mutilated and the hole through the upperlugibecome's worn so that the bolt willl have more Aor'less play, this play in turn tendingtoaggravate the situation and lgradually enlarge the hole in the upper lug. It then becomes to drill out the lugs and insert bushings in them which will be of a suitablesize to receive a new bolt to properly carry the wheel arm.

It is the object of my present invention to produce a tool which Will facilitate the necessary reaming and threading operations involved in making this repair, and which may also be used for inserting the new bushings in their proper positions. p

In the drawings, Fig. l is aside view of my tool, showing it applied tothe. end of an axle; Fig. 2 is a front elevation of the' same;

and Fig. 3 is a view of a special form of reamer; and Figs. 4 and 5 are views of supplementary tool elements.

Similar reference numerals in all the figures.

The frame 1 is made of a size suitablevto slip over the lugs on the end of the axley 2;

and is provided with steadying rods 3,' 3,

which are threadedfinto the' sides of the frame, and are adapted to extend out along,

The screw `4 may thenfbe reversed so'as' to free the frame and allow it to be removed .l

A rearner 16 from the end `ofthe axle.l may then beinserted in place of L9, and the position of the frame relative to the'aXle reversed sokthat the reamer may enter the holejin the upper lug and the screw 4 .center in ythe hole ed with suitable'handle 6,'wherebyit 1 maybe .turned upand'doivnA 'This screwis,

through the lower lug, afterwhich the upper hole may be reamed out conical form by rotating the realmeif,l at the Sametime 'screwing np the sciefv;I 4f.

rIhis Will produce a new conical seat in the upper lug. n

The tool may be used to insert the 'busliings by substituting` a suitably headed tool 17 for the reamer 16, the head of such sub stitute tool being too large toy pass down through the hole in the new, conical bush iii-g 19. The bushing is then `dropped loosely into position in the lue; and may be forced home positively and securely by drawing the headed element down against it by aid ot the sereT il.

The lower bushing- 20, threaded externally and internally, may Abe screwed in placein the lower lug, by providingv it With a suitable cross slot lZ1 tol cooperate with an enelemeiit 22 upon the end of a driver "23, `which may be substituted for the -reamei` 9 or 16 in the smooth 'bearing of Vthe vframe l. If, then the bushingr is started into the newly threaded bore through vthe lug, it may be screwed home by turning' the engaging ele'ii'ient, which may 4be kept to dirty "by gradually turning ldown the screw 'el @as the bushing' is sent home, and this avoids lslipping of the engaging element and mai-ring of the bushing in the process of insertingit.

It is obvious that details of my improved tool might be modified as by the substitution of mechanical equivalents or the like iv-ith- Y, out departing from the spirit of my ii'ivention as claimed.

Havingtlius described my invention, what I claim and desire to secure by Letters Paitent of the United States, is
